本身调试彻底能运行后,写在此,供新人参考,供本身温故apache
一、准备模板文件编程
//以下为hellosite.vm
app
Hello $name! Welcome to $site world!
二、准备Java文件 (补充说明:hellosite.vm、HelloWorld.java放在同一目录下)spa
//以下为HelloWorld.java.net
import java.io.StringWriter; import org.apache.velocity.app.VelocityEngine; import org.apache.velocity.Template; import org.apache.velocity.VelocityContext; public class HelloWorld{ public static void main( String[] args )throws Exception{ /* first, get and initialize an engine */ VelocityEngine ve = new VelocityEngine(); ve.init(); /* next, get the Template */ Template t = ve.getTemplate( "hellosite.vm" ); /* create a context and add data */ VelocityContext context = new VelocityContext(); context.put("name", "Eiffel Qiu"); context.put("site", "http://www.j2medev.com"); /* now render the template into a StringWriter */ StringWriter writer = new StringWriter(); t.merge( context, writer ); /* show the World */ System.out.println( writer.toString() ); } }
3.1 下载jar包调试
http://velocity.apache.org/download.cgi ——>Older releases ——>最终到达 http://archive.apache.org/dist/velocity/engine/1.6.3/,找到 velocity-1.6.3.zip 下载code
3.1 解压velocity-1.6.3.zip ,发现解压后的目录下存在velocity-1.6.3.jar、velocity-1.6.3-dep.jarblog
3.2 配置classpath环境变量,引入velocity-1.6.3.jar、velocity-1.6.3-dep.jarip
四、编译运行上述Java文件,结果以下:
D:\聚划算\技术部\编程练习\Velocity\testVelocity>java HelloWor
Hello Eiffel Qiu! Welcome to http://www.j2medev.com world!
后记:
一、调试过程当中,刚开始在classpath中只设置了velocity-1.6.3.jar,调试后发现缺class,缺的class正好在velocity-1.6.3-dep.jar中,引入后问题解决
